Whole House & Under Bench Water Filters & Purifiers
Rainwater Filtration & Treatment for Home
Rainwater is one of nature’s purest gifts — but by the time it reaches your tank, it’s often far from clean. As rain falls through the atmosphere, it absorbs carbon dioxide, becoming mildly acidic. On its way to your roof, it can also collect dust, organic matter, metals from roofing materials, and even traces of faecal contamination from birds or animals.
These impurities can introduce harmful microorganisms into your tank, affecting the safety, taste, and quality of your water.
That’s where Aqua comes in.
With over 30 years of experience, we provide complete rainwater filtration and treatment solutions — from first-flush systems and UV disinfection to tailored tank maintenance plans. Backed by our nationwide network of water quality specialists, Aqua ensures your family enjoys safe, clean, and great-tasting water, straight from the source.
